我有一个基于Protostar模板的自定义Joomla 3引导程序模板。
目前左侧主要内容区域标记为：
<div class="itemMainContent col-sm-8 col-xs-12">
如果未设置/激活特色图像，则左侧主要内容标记的方式是：
<div class="itemMainContent col-xs-12">
基本如果没有设置右侧边栏/特色图像，主要内容区域应为全宽（12列）。
摘自主内容区域的default.php标记和右侧特色图像侧边栏如下：
<div class="itemMainContent col-sm-8 col-xs-12">

图片似乎包含在$images->image_fulltext中，因此您可以使用empty查看该图片是否存在。
如果图像存在，则仅打印班级名称col-sm-8。
<div class="itemMainContent <?php if (!empty($images->image_fulltext)) echo "col-sm-8" ?> col-xs-12">
对不起，我对Joomla并不熟悉，所以我很好奇如何填充$image变量。考虑到我的解决方案发布在您发布的代码的开头，$image变量可能尚未可用。在这种情况下，您需要先获得它。我怀疑地看着侧栏$params->get('access-view')的第一行。您可能需要先调用它。我希望以后可以再次打电话，但你可能不得不玩它，或者有经验的人可能会参与其中。
